T0 ctZZ whom it 711/11 concern.-

Be it known that I, ERNST WA TER FRIED- RICH SACHSE; a sub ect of theEmperor of Germany, and a resident of Hamburg, in the 1 German Empire,have invented a certain new and useful Improved Fastener for PartlyOpened Doors, IVindows, and the Like, of which the following is aspecification.

The present invention refers to new and useful means for fasteningdoors, windows, shutters, louvers, and the like in a partlyopen state,and more particularly to such means which can be locked by the lock-boltin such manner that the fastener cannot be released or withdrawn byunauthorized persons. The said means consist of a hook which is pivoted,preferably, to the fixed part of the door or door-frame orv like fixedpart and of an eye fastened to or arranged on the movable part of thedoor or the door-wing or the like. This eye is arranged at a shortdistance from the lock-bolt in this manner that when the hook engagesthe said eye and the lock-bolt is in its advanced position it preventsthe disengaging of the hook from the eye, and thus the partly-openeddoor is locked in this position. The disengagement of the fastener isnot possible until the lock-bolt is retracted.

The fastener or locking device is especially applicable on doors onboard of ships, and more particularly for cabin-doors, which frequentlyare held partly open for the sake of ventilation or of allowing theentrance of fresh air when it is desired to make it impossible tocompletely open the door except by the proprietor of the cabin, nomatter whether he is in or out. Since the lock-bolt can only beretracted by means of a key, the proprietor is well sure thatunauthorized persons cannot enter the cabin even. though the same bepartly open.

In the drawings similar letters refer to similar parts.

Figure 1 illustrates part of a cabin-door and its frame in elevationfrom inside with the lock, the door being closed and the hook hangingloosely down. Fig. 2 is a horizontal section of the same part of thedoor and its frame, the door being partly opened and locked in thisposition by the fastener and the lock-bolt. Fig. 3 is a front view ofthe lock in connection with the hook engaging the eye. Figs. l7 show amodification, Fig. 4t being the elevation, and Fig. 5 the horizontalsection, of the lock on the door, and the 7 Figs. 6 and 7 showingsections of the fastener i in two different positions. In theconstructions shown the hook a is pivoted in any suitable manner to thefixed part of the door or the frame I) of the door, and the eye 0corresponding with this hook is attached to the casing d of the lock,preferably between the catch-bolt f, operated by i the handle 6, and thelock-bolt g, operated by a key. On the strike it, arranged on the frameof the door, there is a gap t, Fig. 1, into which the eye 0 projectswhen the door is l closed. I When the door proper or the door-wing 7c isto be held in a partly-open position, the hook a is hooked on the eye 0after the door has been opened to a corresponding extent, as shown inFig. 2, whereupon the lock-bolt g is moved outwardly over the hook a bythe aid of the key (shown in dotted. lines in Fig. 2) to lock the saidhook in this positionthat is to say, the hook is held fast between theeye 0 and the lock-bolt 9, so that it is impossible to disengage thehook from the eye. When it is required to shut the door, the key isturned backward, thus withdrawing the lock-bolt from the hook, whichthen is released from the eye, enabling the door to be closed. The partsare then in the position shown in Fig. 1.

Evidently the mechanisms described so far can be modified in differentways. The 1 eye 0 may be arranged 011 any other part of E the lock or ofthe doorfor instance, above f the lockbolt-in which case the latter actson l the hook from below. The arrangement also maybe reversedthat is tosay, the eye may be fastened to the frame and the hook pivoted to thelock or the door. In the latter instance the lockbolt may also bearranged to act on the hook. The main point is that the fastener,consisting of hook and eye, can be locked by the lock-bolt, or even bythe I catch-bolt, in such manner that it is impossible for anyunauthorized person to undo i the locking. I Instead of fastening theeye firmly to the lock and making a gap on the strike the eye may bemade to slide in the case of the lock. I In the modification shown inFigs. 4-7 the l push-bolt or night-boltlis provided with an opening orperforation 0, thus serving as an eye, in such manner that this eyeprojects from the door only when the night-bolt Z is moved outwardly bythe thumb-piece Z.

When the door is opened to the extent corresponding to the length of thehook a, the night-bolt is pushed outwardly and the hook engaged with theopening 0 of the nightbolt, whereupon tile lock-bolt is moved outwardlyby turning the key, thus locking the hook in engagement with the eye.The night-bolt 1 may be beveled on one side or rounded off on its pointn, by means of which the projecting bolt is automatically moved inwardwhen, the door is shut by the beveled point a contacting with the edgeof the strike. The thumbpiece l also may be provided. with a perforation0 into which the hook may engage, Fig. 7. The thumb-piece having thesame height as the bolt Z the hook when hooking into its perforation 0may be locked in the same manner by means of the lock-bolt 9, Fig. 7, aswhen it engages the perforation c of the bolt Z itself, Fig. 6. Thusmeans are provided for to open the door more or less, as circumstancesmay require or as desired.

1 claim 1. The combination with a door, of a lock thereon, an eye on thelock in proximity to the usual locking-bolt thereof and a hook hinged.to the door-jamb, said hook adapted to engage the eye and be heldtherein by the bolt when thrown, substantiall as described.

2. The combination with a door having a 1 lock provided with the usuallocking-bolt, of Q a hook hinged to the jamb, and a slidable eye 5 inthe lock proximate the locking-bolt, said hook adapted to enter the eyeand be locked seam 1 against removal therefrom when the bolt is thrown,substantially as described.

3. The combination with a door having a lock provided with the usuallocking-bolt, of a hook hinged to the jamb, a sliding member on the lockproximate to and below the bolt, and a member fixed on the slidingmember, said hook adapted to be locked in engagement between either thesliding member or the member fixed thereon and the bolt, when the latteris thrown.

4. A fastener for doors consisting of a hook pivotally attached to theframe of the door and a night-bolt on the door having at its front end aperforation thus forming an eye into which the hook engages, when thedoor is partly open, in combination with a lockbolt adapted to lock thehook, when it engages the eye.

5. A fastener for doors consisting of ahook pivotally attached, to theframe of the door, and anight-bolt slidable in the lock of the door andhaving at its front end aperforation thus forming an eye into which thehook may engage, and a second. perforation in the thumb-piece of thesaid bolt, into either of which perforations the hook may engage, whenthe door is partly open, in combination with a lock-bolt adapted to lockthe hook, when it engagesone of the perforations.
